Description

Technical Field

[0001] This application relates to the field of optical communication technology, and in particular to a miniaturized optical cable junction box. Background Technology

[0002] Optical cable junction boxes are one of the core products in optical fiber access networks. They are generally used at the user aggregation point of optical fiber access. The products have a large optical fiber capacity and typically need to perform a large number of functions such as optical fiber splicing, optical fiber termination, and optical fiber splitting inside the product.

[0003] In the existing technology, optical cable junction boxes are usually composed of a door panel, a box body, and internal components. The internal components are usually fixed in the box body. The internal components include fusion splicing modules, termination modules, and splitting modules. When it is necessary to operate these modules, it is usually necessary to reach into the box body. In order to ensure sufficient operating space, the internal space of the box body is usually designed to be large, and the functional modules are also confined to the front where they are easily accessible to the hands.

[0004] Because most fiber optic junction boxes are relatively large, they occupy a significant amount of ground space during installation. However, in most urban settings, especially in city centers and commercial areas, land resources are scarce. Therefore, obtaining land approval for the installation of fiber optic junction boxes is a major challenge in the construction of fiber optic access networks. Summary of the Invention

[0017] The frame is arranged from top to bottom on the wall away from the telescopic component, including a pigtail management module, a fusion splicing module, an optical fiber management module, and an optical fiber fixing module.

[0018] In some embodiments, the telescopic assembly is rotatably connected to the internal component via a pivot.

[0019] And / or, the housing and the door panel are connected by an embedded hinge;

[0023] And / or, an operating table is rotatably provided on the inner wall of the door panel, and a support platform located below the operating table is also provided on the inner wall of the door panel. A support rod is rotatably connected to the operating table, and when the support rod rotates to abut against the support platform, the operating table is in a horizontal state.

[0024] And / or, the bottom of the enclosure is equipped with several cable sealing modules for the entry and exit of optical cables;

[0025] And / or, the bottom of the enclosure is provided with a floor mounting base.

[0026] In some embodiments, the housing has an open top cover, and a cable sealing module for optical cable entry and exit is installed in the opening provided on the open top cover.

[0027] In some embodiments, the top cover of the enclosure has openings on both sides, with a cable sealing module installed on one opening and a blind hole sealing module installed on the other opening; or, the top cover of the enclosure has two mutually perpendicular axes of symmetry, one of which is the line connecting the midpoints of the two wide sides of the top cover, and the other is the line connecting the midpoints of the two long sides of the top cover, and there is one opening, located on one of the two sides of the top cover of the enclosure;

[0033] The beneficial effects of the technical solution provided in this application include:

[0034] The optical cable junction box provided in this application embodiment has an internal component rotatably connected to one end of a telescopic assembly, while the other end of the telescopic assembly is fixed to the inner wall adjacent to the box body and the door panel. Since the telescopic assembly can extend and retract, when it is necessary to operate the various functional modules on the internal component, the internal component can be dragged outward, and the telescopic assembly will extend accordingly, thereby allowing the internal component to extend out of the box body and utilize the space outside the box body for operation. Since the internal component is rotatably connected to the telescopic assembly, when it is necessary to operate the functional modules on the side or back of the internal component, the internal component can also be rotated for operation. After the operation is completed, the internal component can be rotated back to its original position, and then the internal component can be pushed into the box body, allowing the telescopic assembly to retract, thereby returning the internal component to the inside of the box body, and finally the door panel can be locked.

[0035] As can be seen, this application designs the push-pull and rotation operations of the internal components, which enables it to make full use of the external space to achieve the operation of the various functional modules on the internal components. In this way, while ensuring sufficient operating space, the size of the optical cable junction box is reduced, the land area occupied by the optical cable junction box is reduced, and land resources are saved.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in the figure, this application provides a miniaturized optical cable junction box, which includes a box body 1, a door panel 2, an internal component 3, and a telescopic assembly 4. The box body 1 is provided with a door panel 2, which is used to open and close the box body 1. The telescopic assembly 4 is located on the side wall of the box body 1, and the side wall is adjacent to the door panel 2. One end of the telescopic assembly 4 is fixed to the side wall, and the other end is rotatably connected to the internal component 3, and is used to extend or retract, so that the internal component 3 extends out of or returns to the inside of the box body 1.

[0057] The optical cable junction box provided in this application embodiment has an internal component 3 rotatably connected to one end of a telescopic assembly 4, while the other end of the telescopic assembly 4 is fixed to the inner wall adjacent to the box body 1 and the door panel 2. Since the telescopic assembly 4 can extend and retract, when it is necessary to operate the various functional modules on the internal component 3, the internal component 3 can be pulled outward, and the telescopic assembly 4 will extend accordingly, thereby allowing the internal component 3 to extend out of the box body 1 and utilize the space outside the box body 1 for operation. Since the internal component 3 is rotatably connected to the telescopic assembly 4, when it is necessary to operate the functional modules on the side or back of the internal component 3, the internal component 3 can also be rotated for operation. After the operation is completed, the internal component 3 can be rotated back to its original position, and then the internal component 3 can be pushed inward into the box body 1, allowing the telescopic assembly 4 to retract, thereby returning the internal component 3 to the inside of the box body 1. Finally, the door panel 2 is locked.

[0058] As can be seen, this application designs the push-pull and rotation operation of the internal component 3, which enables it to make full use of the external space to realize the operation of each functional module on the internal component 3. In this way, while ensuring sufficient operating space, the size of the optical cable junction box is reduced, the land area occupied by the optical cable junction box is reduced, and land resources are saved.

[0059] It is understood that in this application, the housing 1 has three side walls, one of which is the rear side wall opposite to the door panel 2. Of the other two parallel and opposite side walls, one is the left side wall and the other is the right side wall. The telescopic assembly 4 can be installed on either the left or right side wall. Since the door panel 2 is usually installed on the left side wall to rotate and open to the left, for easier operation and to better suit operating habits, see [reference needed]. Figure 1 and Figure 2 As shown, the telescopic component 4 is installed on the right side wall.

[0060] To enable the internal component 3 to extend from or retract into the housing 1, this application also provides a specific structure for the telescopic assembly 4, see [link to details]. Figure 5 and Figure 6 As shown, the telescopic assembly 4 includes a fixed column 5, a movable column 6, a vertical sliding groove 7, and two telescopic arms 8. The fixed column 5 is provided with the vertical sliding groove 7. The movable column 6 is rotatably connected to the internal component 3 and is also provided with the vertical sliding groove 7. The two telescopic arms 8 are arranged crosswise and rotatably connected. One end of each telescopic arm 8 is rotatably connected to the fixed column 5 and the movable column 6, respectively, and the other end is movably disposed in the vertical sliding groove 7 of the fixed column 5 and the movable column 6 respectively through a sliding pin.

[0061] When the internal component 3 is pulled outward, the movable column 6 will move outward accordingly. Due to the presence of the vertical sliding groove 7, the movable column 6 will drive the two telescopic arms 8 to rotate and extend, thereby achieving the purpose of elongation. When the internal component 3 is pushed inward, the two telescopic arms 8 will move in opposite directions and finally retract.

[0062] Understandably, multiple sets can be configured, with two telescopic arms 8 forming a group, depending on the length of the fixed column 5 and the movable column 6. For example... Figure 6 The device is equipped with two sets of telescopic arms 8 to prevent uneven local force from causing jamming and resulting in unsmooth movement.

[0063] The application adopts the above-mentioned cross telescopic arm 8 scheme to achieve telescopic movement. The reasons include at least the following: Firstly, the structure is simple and efficient, and setting the structure in the already small box 1 will not take up too much space in the box 1; secondly, multiple sets of telescopic arms 8 can be added according to the actual situation to achieve uniform force distribution and ensure smooth movement.

[0064] It is understandable that, in addition to the above-mentioned cross telescopic arm 8 solution, other solutions can be adopted, such as installing a cylinder or hydraulic cylinder on the side wall to drive the column 6 by using the telescopic shaft of the cylinder or hydraulic cylinder to push and move it, thereby achieving telescopic movement.

[0065] To further ensure smooth movement of the movable column 6, the telescopic assembly 4 provided in this application also includes a guide mechanism, see [link to application]. Figure 2 As shown, the guiding mechanism includes a guide member 9 and a horizontal guide groove 10. The horizontal guide groove 10 can be formed by bending sheet metal parts. The guide member 9 is provided on the movable column 6, and the horizontal guide groove 10 is provided on the side wall of the box body 1.

[0066] It is understandable that two of the aforementioned guiding mechanisms can be set up, one above the other, such as... Figure 2 As shown, a horizontal guide groove 10 is provided above the top of the fixed column 5, and a horizontal guide groove 10 is also provided below the bottom of the fixed column 5.

[0067] Further, see Figure 2 and Figure 6 As shown, the internal component 3 is also provided with a guide 9, and when the internal component 3 extends out of the box 1, the guide 9 slides out from the horizontal guide groove 10. The advantage of providing the guide 9 on the internal component 3 is that, under the guidance and constraint of the horizontal guide groove 10, the internal component 3 can be pushed into the box 1 more smoothly.

[0068] It is understandable that the guide component 9 can be made of bolts, etc. In order to reduce friction, preferably, the guide component 9 is made of rollers. Rolling friction is relatively less than sliding friction, so the operator can push and pull with less force, which is more labor-saving and worry-free.

[0069] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in this application, the internal component 3 includes a frame that is rotatably connected to the telescopic assembly 4. When the frame returns to the interior of the housing 1, a splitter module 11, a termination module 12, and a docking module 13 are arranged sequentially from top to bottom on the wall of the frame facing the door panel 2. A splitter pigtail management module 14 is also provided on the side of the termination module 12. A pigtail management module 15, a fusion splicing module 16, an optical fiber management module 17, and an optical fiber fixing module 18 are arranged sequentially from top to bottom on the wall of the frame away from the telescopic assembly 4.

[0070] This application also designs a fiber optic cabling path suitable for this layout. Taking the cable entry and exit points at the bottom of enclosure 1 as an example, see... Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the housing 1 is equipped with several cable sealing modules 30 for optical cable entry and exit, and the rear side wall of the housing 1 is provided with fiber routing units 45.

[0071] The input optical cable enters the housing 1 through the cable sealing module 30 at the bottom, and then branches out into the input optical fiber (marked as A). After running on the fiber routing unit 45 on the rear side wall of the housing 1, the input optical fiber A is fixed on the fiber fixing module 18 and then enters the fusion splicing module 16 to be fused with the input pigtail (marked as C). The input pigtail C goes around the pigtail management module 15, passes through the pigtail inlet and outlet 46 on the pigtail management module 15, and then runs downward from the back of the pigtail management module 15 to the termination module 12. The termination module 12 terminates the input pigtail C with the splitter input pigtail (marked as E). The splitter input pigtail E goes through the front of the termination module 12, goes upward around the splitter pigtail management module 14, and then enters the splitter module 11. The optical signal is transmitted to the splitter module 11 through the splitter input pigtail E and is split.

[0072] After splitting, the output pigtail (marked as F) is output from the splitter output end. The output pigtail F comes out from the splitter module 11, passes through the splitter pigtail management module 14, and enters the termination module 12. The termination module 12 terminates the output pigtail F and the output pigtail (marked as D). The output pigtail D comes out from the back of the termination module 12, passes upward through the pigtail inlet and outlet 46 on the pigtail management module 15, passes through the pigtail management module 15, and is fused with the output optical fiber (marked as B) on the fusion splice module 16. The output optical fiber B runs on the fiber routing unit 45 on the rear side wall of the housing 1 and exits the housing 1 from the cable sealing module 30 at the bottom.

[0073] See Figure 5 and Figure 6 As shown in this application, the telescopic component 4 and the internal component 3 are rotatably connected via a rotating shaft 19; it is understood that multiple rotating shafts 19 may be provided.

[0074] To improve the anti-theft capabilities of the junction box, see [link / reference]. Figure 7 As shown in this application, the box body 1 and the door panel 2 are connected by an embedded hinge 20; thus, when the door panel 2 is closed, the gap between the door panel 2 and the box body 1 is extremely small. On the one hand, the sealing performance is good, preventing rainwater from entering; on the other hand, it is difficult to pry open with tools, thus improving the anti-theft capability.

[0075] Further, see Figure 8 As shown, the door panel 2 includes an outer layer and an inner layer that are interconnected. This application provides a door panel reinforcement 21 between the outer and inner layers. By providing the door panel reinforcement 21, the strength of the door panel 2 is increased, thereby improving its anti-theft capability. It is understood that the aforementioned door panel reinforcement 21 can be formed by bending sheet metal parts, and multiple door panel reinforcements 21 can be provided.

[0076] Further, see Figure 9 As shown, the enclosure 1 includes an outer layer and an inner layer connected to each other. A corner reinforcement 22 is provided between the outer layer and the inner layer and at a corner of the enclosure 1. By providing the corner reinforcement 22, the strength of the enclosure 1 is improved, thereby enhancing its anti-theft capability. It is understood that the corner reinforcement 22 can be formed by bending sheet metal parts, and multiple corner reinforcements 22 can be provided.

[0077] Further, see Figure 1 As shown, a lock rod guide seat 23 is provided on the inner wall of the door panel 2. The lock rod 25 of the anti-theft lock 24 installed on the door panel 2 passes vertically through the lock rod guide hole of the lock rod guide seat 23, and a lock rod pin hole 26 adapted to the lock rod 25 is provided inside the box body 1. Since the lock rod 25 is relatively long, by setting the lock rod guide seat 23 and the lock rod pin hole 26, the bending resistance of the lock rod 25 can be enhanced. When the door panel 2 is pulled outward with force, since one end of the lock rod 25 passes through the lock rod guide seat 23 and the lock rod pin hole 26, and the other end is connected to the anti-theft lock 24, when the door panel 2 is pulled outward, the lock rod 25 is subjected to force at the lock rod guide seat 23, the lock rod pin hole 26 and the anti-theft lock 24, making it difficult for the lock rod 25 to bend and open the door panel 2, thereby improving the anti-theft capability of the junction box.

[0078] As can be seen, in Figure 1In the middle, there are two locking rods 25, one above the other. Each locking rod 25 is equipped with a locking rod guide seat 23. The locking rod pin hole 26 of the lower locking rod 25 is located at the bottom of the housing 1. See Figure 10 As shown, the upper locking rod 25 is equipped with a locking rod pin hole 26 on the top of the housing 1. When the anti-theft lock 24 is tightened, the two locking rods 25 move closer together to unlock, thereby opening the door panel 2, or move further apart to insert into the corresponding locking rod pin hole 26 to lock.

[0079] Further, see Figure 1 As shown, an operating table 27 is rotatably mounted on the inner wall of the door panel 2, and a support platform 28 located below the operating table 27 is also provided on the inner wall of the door panel 2. A support rod 29 is rotatably connected to the operating table 27, and when the support rod 29 rotates to abut against the support platform 28, the operating table 27 is in a horizontal state.

[0080] When the control panel 27 is retracted, the support rod 29 can be attached to the back of the control panel 27. In order to fix the support rod 29, a latch 47 is also provided on the back of the control panel 27, and the support rod 29 can be latched into the latch 47.

[0081] Further, see Figure 1 As shown, the bottom of the housing 1 is equipped with several cable sealing modules 30 for optical cable entry and exit; it can be seen that this application allows optical cables to enter and exit from either the top or the bottom. The appropriate method can be chosen flexibly based on the actual installation site conditions.

[0082] See Figure 1 , Figure 2 , Figure 11 , Figure 12 , Figure 13 As shown, the housing 1 has an open top cover 32, and a cable sealing module 30 for optical cable entry and exit is installed on the opening 31 provided on the open top cover 32, thereby realizing the purpose of optical cable entry and exit from the top.

[0083] Understandably, the open top cover 32 can be detachably mounted on the top of the housing 1 using screws or the like.

[0084] If no cable entry / exit is required at the top of housing 1, then the sealing of opening 31 becomes an issue. This application provides two exemplary solutions. For example, as an example, in one solution, see [link to solution]. Figure 14 As shown, the enclosure 1 is equipped with a closed top cover 34. The closed top cover 34 and the open top cover 32 are selectively installed on the top of the enclosure 1. If cable access is required at the top, the open top cover 32 is installed on the top of the enclosure 1; if cable access is not required at the top, the closed top cover 34 is used instead. For example, as an example, in another solution, see [link to solution]. Figure 12As shown, the open top cover 32 is equipped with a blind hole sealing module 33. The blind hole sealing module 33 is installed on the opening 31 to achieve the sealing of the opening 31.

[0085] Due to the complexity of the on-site fiber optic cable layout, it may be necessary to change the positions of the top-mounted incoming and outgoing cables. Therefore, to allow for more flexible fiber optic cable layout, this application provides two exemplary solutions for changing the position of opening 31. For example, as an example, in one solution, see... Figure 12 and Figure 13 As shown, the top cover 32 of the housing 1 has openings 31 on both sides. A cable sealing module 30 is installed on one opening 31, and a blind hole sealing module 33 is installed on the other opening 31. Depending on the actual situation, the positions of the cable sealing module 30 and the blind hole sealing module 33 can be changed, thereby allowing the opening 31 where cables need to enter or exit to be changed. For example, as an example, in another solution, see [link to solution]. Figure 11 As shown, the top cover 32 of the box body 1 has two mutually perpendicular axes of symmetry. One axis of symmetry is the line connecting the midpoints of the two wide sides of the top cover 32, and the other axis of symmetry is the line connecting the midpoints of the two long sides of the top cover 32. There is one opening 31, which is located on one side of the top cover 32 of the box body 1. In this solution, the top cover 32 is a symmetrical structure with the opening 31 on one side. The position of the opening 31 can be changed by rotating the top cover 32.

[0086] In addition, the closed top cover 34 and the open top cover 32 can be designed to be inclined to facilitate rainwater sliding off.

[0087] The closed top cover 34 and the open top cover 32 are designed with screw holes on the side near the door panel 2. The closed top cover 34 and the open top cover 32 can only be removed after the door is opened, which has better anti-theft performance.

[0088] Further, see Figure 15 As shown, the top cover of the opening is provided with a top shielding cover 35 for shielding the cable sealing module 30.

[0089] In this application, the enclosure 1 has at least two installation options. For example, as an example, it can be installed on a floor. For details, see [link to relevant documentation]. Figure 1 As shown, a floor mounting base 36 is provided at the bottom of the box 1.

[0090] For example, as an illustration, a pole-mounted installation method can be used; see details below. Figure 15 As shown, a pole mounting assembly 37 for mounting on the pole is provided on the side wall of the housing 1.

[0091] Furthermore, to facilitate installation, this application provides a specific construction for the pole mounting assembly 37; for example, see [reference needed]. Figure 1 and Figure 15 As shown, the pole mounting assembly 37 includes a pole support 38 and clamps 39. The pole support 38 is mounted on the housing 1, and has clamp holes 40 for the clamps 39 to pass through. In use, the clamps 39 are passed through the clamp holes 40 on the pole support 38 and then fastened to the pole. It is understood that multiple clamps 39 can be provided.
